摘要
广西容县温风铜锌矿床位于钦-杭成矿带南西段,矿体呈脉状产于晚侏罗世钾质花岗岩中,严格受构造破碎带控制,矿石矿物有闪锌矿、黄铜矿、辉银矿等。文章在总结矿床地质特征的基础上,结合流体包裹体及H、O、S同位素研究,探讨矿床成因。研究结果表明成矿物质为岩浆来源,成矿流体来源于岩浆水和大气降水混合,具有中温的特征。认为温风铜锌矿床属与岩浆活动有关的中温热液充填矿床。
The Wenfeng Zn-Cu deposit located in the southwestern part of the Qin-Hangzhou metallogenic belt,the orebody occurs in the late Jurassic granite as veins and,controlled by the fault structure,the main ore minerals include zincblende,copper pyrites,argentite.Basing on summarizing the geological characteristics of deposit,Combined with fluid inclusions and H,O,S isotope studies,this paper discuss the genesis of ore deposit.The results show that the metallogenic material was from source magma.,the ore-forming fluid was medium temperature,from mixture fluid of magmatic water and atmospheric precipitation。Wenfeng Zn-Cu deposit was a Medium temperature filling deposit related with magmatic activity.
